TeamFortress.de somehow got their hands on the 36 new achievements for the Medic:
From looking at them, it appears that a player going through them all will be an excellent medic - answers calls from his teammates, spreads ubercharge between a few people, saving teammates from near-deaths by fire or falling, and generally kicking ass
I believe that this is directly linked to the statistics that show Medic the least played class.
